/* A C compound statement that outputs the assembler code for a thunk function,
    used to implement C++ virtual function calls with multiple inheritance.  The
    thunk acts as a wrapper around a virtual function, adjusting the implicit
    object parameter before handing control off to the real function.

    First, emit code to add the integer DELTA to the location that contains the
    incoming first argument.  Assume that this argument contains a pointer, and
    is the one used to pass the this' pointer in C++.  This is the incoming
    argument *before* the function prologue, e.g. %o0' on a sparc.  The
    addition must preserve the values of all other incoming arguments.

    After the addition, emit code to jump to FUNCTION, which is a
    FUNCTION_DECL'.  This is a direct pure jump, not a call, and does not touch
    the return address.  Hence returning from FUNCTION will return to whoever
    called the current thunk'.

    The effect must be as if FUNCTION had been called directly with the adjusted
    first argument.  This macro is responsible for emitting all of the code for
    a thunk function; FUNCTION_PROLOGUE' and FUNCTION_EPILOGUE' are not
    invoked.

    The THUNK_FNDECL is redundant.  (DELTA and FUNCTION have already been
    extracted from it.)  It might possibly be useful on some targets, but
    probably not.

    If you do not define this macro, the target-independent code in the C++
    frontend will generate a less efficient heavyweight thunk that calls
    FUNCTION instead of jumping to it.  The generic approach does not support
    varargs.  */
